Conduction system pacing using a rotatable connector enabling continuous pacing during lumenless lead deployment: a case report.

ABSTRACT:

Background

Conduction system pacing (CSP) is an alternative to right ventricular pacing, providing more physiological ventricular activation. Current guidelines recommend CSP for patients with an expected ventricular pacing burden >20% and mildly reduced left ventricular ejection fraction. However, consistent conduction capture is not always achieved, with success rates of around 80% in the MELOS trial. Lumenless leads (LL) are widely used for CSP, but sustained, real-time pacing and impedance monitoring could enhance procedural control and decrease procedure time. The integration of a tool to overcome this limitation was highlighted as a future development in the 2025 EHRA CSP consensus. We report the first case using this approach.
